Internet Slow, Start up slow - Hijackthis Log Included

PC has been quite slow recently on starting up. Harddrive has been a bit louder aswell. I get A LOT of random ping flucuations when im playing games (like counterstrike) which have gone down a bit when i did an AD-AWARE scan.

Already done an ad-aware se scan and a nod32 scan both have found some items and removed them. Any pointers from the log? Im on Vista Ultimate 64bit
